This is my favourite workshop item. I have been at night school for a year learning to TIG weld. I bought this welding machine new at an end-of-year sale. It was about $1500, if my memory serves me correctly, and the subsequent purchase of a genuine foot control was about $250.
I talked to our welding supervisor at work, and he seemed to think the Uni equipment is ok. We have no problem getting our plasma cutter serviced if it has a problem. Also, if you call their head office number in Sydney, you get to speak to a REAL Australian person who knows something about their products.
This is an AC/DC machine and good for 200A, which I have discovered is sufficient to melt my largest 2.4mm electrodes. It has high frequency start, pulse, and all the AC balance controls required to AC weld aluminium.
The front panel is pretty intimidating for a noobie but I have got half an idea what I am doing after a lot of classes.
Since most of my project feature “thin” materials, the TIG will be the mainstay of the welding machine fleet (I also have a UniMig ProCraft 240, an Oxy/Acetylene rig, plus a el-cheapo plasma cutter on the way from eBay).
When I use this on subsequent projects, I will make a note of the settings I use and post them along with the project.
